JOSEPH EDGEUOMB, OF VVORGESTER, MASSACHUSETTS.

Specification forming part of Letters Patent No. 44,294, dated September 20, 1864.

To all whom it may concern:

Be it known that I, JOSEPH EDGECOMB, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Glue and Water Heaters as applied to Kerosene and other Lamps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which- Figure 1 represents a perspective view ot said apparatus. Fig. 2 represents a longitudinal vertical section through the same, showiug the lamp, its burner, and chimney in a side view.

My invention consists in the combination, with a lamp and waterreceptacle, of a conical reflector, by means of which the heat radiated from the lamp is reflected on the bottom of the water-receptacle, and whereby a high degree of heat is obtained by the use of a comparatively small amount of burning-fluid.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents the lamp and oil-receptacle.

B represents the burner and 0 the chimney of an ordinary kerosene lamp. The oilreceptacle is somewhat large in proportion to its height, to support the entire apparatus.

D represents three or more socket-tubes, secured to the top of the lamp A, which receive a corresponding number of pins, E, of the conical reflector F, and by means of which said reflector is attached to or detached from the lamp, the sockets D and pins E being of sufficient length to hold the reflector F firmly. A horizontal flange, G,- is secured to the upper end of the reflector F, and is provided with holes a for the escape of the gases of combustion and to keep up the supply of air in the lamp. The cylindrical rim 1-1 is secured 'to the flange G, and serves to support the waterreceptacle I, in which the water is heated, and in which the glue'pot or other article to be heated is placed. The reflector F and the parts attached thereto are so arranged on the lamp that the lamp chimney stands concentrically within the same. The action of the reflector is as follows: In using an ordinary kerosene lamp a great amount of heat is radiated from the sides of the chimney, particularly from the upper part, which becomes the hottest. This heat is radiated horizontally, and in placing a vessel above the chimney that heat only which escapes through the orifice of the lamp-chimney strikes the bottom of such vessel, while the radiating heat escapes horizontally and is lost. This radiated heat is all economized by means of my reflector, as the heat radiated from the chimney is all reflected upon the bottom of the vessel, as represented in red lines in Fig. 2, and I am thus enabled to obtain a high degree of heat by means of "a proportionate small amount of oil. This heater is particularly applicable for heating glue, as the entire arrangement is extremely simple, and, the lamp being highly economizing, the glue can be kept warm at the trifling expense of a few cents a day when coal-oil or kerosene is used, the glue being protected from burning by setting the glue-pot into the water-receptacle 1.

Pieces of isinglass may be set into the openings b of the reflector F, or its sides may be made partially of isin glass, whereby the light from the lamp can be used to work by, and also to enable the workmen to regulate the flame without taking 0d the glue-pot or the water-receptacle.

Slides may be arranged to slip over the isinglass windows when light is not wanted, and the apparatus may thus also be used as a night or nursery lamp.

On removing the reflector F the lamp can be used as an ordinary lamp for all practical purposes without in the least changing any of its arrangements.

This lamp is an excellent article for various uses in the household and workshop. Its perfect ventilation by means of the holes a prevents any disagreeable smell or obnoxious gases, and it is highly economical in its application.

If desirable, two or more burners may be used within the reflector F to produce a high degree of heat or to heat large vessels.

Having thus fully described the nature of myinvention, whatl claim herein as new, and desire to secure by Letters Patent, is-

1. The combination of the conical reflector F with the lamp and water-receptacle, substantially in the manner and for the purposes herein described.

2. Attaching the reflector F to the lamp in such a manner that it can readily be removed other, and when constructed and arranged as therefrom and that when removed the lamp herein shown and described. may be used as an ordinary lamp substantially in the manner herein described; JOSEPH EDGECOMB' 3.
